Good hair ties that won't stretch out?

Long haired hippies! What do you use everyday to keep your hair back? I've always bought cheap hair ties at Walmart. Lately though, the brands there are stretching out in their very first use. Could you suggest some high quality pony-tail holders?

FWIW, I'm hard on them, I twist three times to get them tight enough. Thanks for your help with such a mundane question!
